luxurious growth of grass
蔘 centers on the idea of lush, abundant growth of grass or vegetation, suggesting a scene of thick, thriving plant life.
蔘 combines the grass radical 艹 with 參, which likely contributes a phonetic element. The exact historical development is uncertain, but the character is associated with lush vegetation.
The grass radical 艹 sits above 參, which resembles a person with flowing hair. Imagine a person standing in a field where the grass grows so thick and luxurious that it reaches up to their shoulders.
For シン, picture a lush green scene where the grass is so thick it looks like a shin-deep carpet: shin -> シン, and you're wading through the luxurious growth.
